Tonberry Bookshelf ★

Taken all the way down to base materials, one Tonberry Bookshelf is 3 crafting steps deep and needs 5 intermediates — Rosewood Lumber ×5, Spruce Lumber ×5, Electrum Ingot ×2 and 2 others — which resolve to 8 distinct raw materials totalling 44 units, plus 67 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,302 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 62 are burned by the intermediates, so the real crystal cost is 40 Wind Shard, 18 Wind Crystal, 5 Lightning Shard and 2 other kinds.

The chain crosses four disciplines — Carpenter to Lv 50, Weaver to Lv 43, Goldsmith to Lv 42 and Alchemist to Lv 25 — so no single class can finish it unaided.

5 of the 8 raw materials come out of the ground, and one of them is time-gated: Spruce Log (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
